A sound reinforcement system is the combination of microphones, signal processors, amplifiers, and loudspeakers in enclosures all controlled by a mixing console that makes live or pre-recorded sounds louder and may also distribute those sounds to a larger or more distant audience. [1][2] In many situations, a sound reinforcement system is also ...
The Hafler circuit is a passive electronics circuit with the aim of getting derived surround sound or ambiophony from regular stereo recordings without using costly electronics. Such circuits are generally known as matrix decoders. The Dynaquad system works using similar principles. [1]
Wall of Sound (Grateful Dead) A model of the "Wall of Sound", on display at the Dead Forever Experience exhibit at the Venetian.

The term backline is used in popular music and sound reinforcement system contexts to refer to electronic audio ...
The inset shows the electronic simulation. Notably, such electronic systems require more than one speaker. Time difference in a stereophonic recording of a car going past. Stereophonic sound, or more commonly stereo, is a method of sound reproduction that recreates a multi-directional, 3-dimensional audible perspective.
Quadraphonic sound. Quadraphonic (or quadrophonic and sometimes quadrasonic) sound – equivalent to what is now called 4.0 surround sound – uses four audio channels in which speakers are positioned at the four corners of a listening space. The system allows for the reproduction of sound signals that are (wholly or in part) independent of one ...
The left and right surround speakers in the bottom line create the surround sound effect. 5.1 surround sound ("five-point one") is the common name for surround sound audio systems. 5.1 is the most commonly used layout in home theatres. [1] It uses five full bandwidth channels and one low-frequency effects channel (the "point one"). [2]
Smaart (System Measurement Acoustical Analysis in Real Time) is a suite of audio and acoustical measurements and instrumentation software tools [1] introduced in 1996 by JBL 's professional audio division. It is designed to help the live sound engineer optimize sound reinforcement systems before public performance and actively monitor ...
